TOC-760 hopper oven controller
Recommended equipment: hopper oven (Electric, Gas)
Characteristic
This controller is mainly applied to hopper convection oven, and its operation is simple and convenient. TOC-760 hopper oven controller can select time control, core temperature control or two control methods combining to obtain best baking effect. It has count-down time control, two working modes: automatic or manul and humanized design: as soon as external signal triggered, it enters automatic working state. It has relay switch quantity controller output, and LED luminescent tube coordination indication on panel when it works, can indicate working state of machine with great clarity and simplicity, and is more safe and convenient for users to work.
1、Function characteristics
1）、Using high speed CPU chip design, with rapid movement, accurate control and good stability;
2）、Digitron and indicator light combined display working and alarm state;
3）、Ninety-nine groups baking data storage;
4）、Password setting and data locking avoid operator changing information at will;
5）、Temperature display range: 0～400℃,display precision±1℃；
6）、Range of temperature control: 0～300℃,control precision±1℃;
7）、Range of time setting 0～99 Min, timing precision 1 Sec, timing method: count-down;
8）、Rich temperature control modes (PID control, etc);
9）、Multi-section steam spraying mode;
10）、Booking setting start function;
11）、External triggered start function;
12）、Can select time control, core temperature control or two control methods combining;
13）、Intelligent hopper management, five grades windspeed control output;
14）、Thermocouple temperature signal input;
15）、Fan overload protection and intelligent alarm make equipment work at safe condition.
2、Technical parameter
1）、Temperature, baking time, steam times, core temperature and storage number showed respectively on five-group digitron.
2）、Output control:( switch output)
Heating output one-channel;
Steam output one-channel;
Exhaust output one-channel;
Lighting output one-channel;
Positive rotating fan output one-channel;
Negative rotating fan output one-channel;
Fan speed output one-channel;
Strong exhaust output one-channel;
Alarm output one-channel;
Power Sync output one-channel.
3）、Input signal: (except thermocouple, the input signal disconnection is effective)
K-type thermocouple input duplex;
Door switch signal input one-channel;
Fan overload input one-channel;
External signal triggered input one-channel;
Standby signal input one-channel.
4）Working power:50～60Hz AC220V±10%. 1、Cautions in installation
1）、External power supply have abnormal changes will lead to the breakdown of control system, for the safety work of the whole system, please make sure to set safety circuit outside of the control system.
2）、Operator must acquaint himself with the contents of manual before installation, wiring, operation and maintenance. And operator must know very well related mechanical and electronic common sense and all relevant safety cautions.
Notice: Improper operation may cause hazards, including personal injury or equipment accident.
3）、Please install on metal or other flame retardant matters and away from fuel.
4）、Should be safety grounding when use.
5）、Wiring operation must be done by professional electrician.
After the disconnect power is confirmed, operation could be started.
2、System installation and commissioning
1）、Should install electricity box of controller in place with good ventilation, oil-proofing and dust proof. If the electric control box is closed, temperature of controller will be too high, affect the normal work and the exhaust fan should be installed; the preference temperature of electricity box is below 50℃ and relative humidity less than 85%RH.
2）、It is necessary to avoid controller being installed too close to AC accessories: contactor, transformer, and so on, for avoiding unnecessary interference and affecting the normal work.
3）、Please have regular maintenance to ensure controller works without accident.
